@Huy is Win10 Home objectively better than Win8.1 Pro?

Huy

Can't really answer that objectively.

0celo7

@Huy Relax that a bit then.

Huy

I think for most users it would be, because most users hated the Win8 UI. I didn't, so I just updated to be up to date.

@0celo7: QQ

0celo7

QQ?

Huy

:P

@0celo7: It's just a bit different in the way to use, apart from that it's not that different. And the privacy stuff that you can disable if you're scared.

Pretty sure Bootcamp was updated for Win10 already, no?

0celo7

16:03

The free update is for the Home version. I have 8.1 Pro. Will I lose any features?

@Huy Yes.

I'm scared about updating though.

Huy

Dunno, you have to google. I had 8.1 Pro and got 10 Pro.

0celo7

I'm also scared about disrupting my Skyrim mods.

Huy

Always backup

0celo7

Did you get the free update?

Huy

Don't you have some proper mod manager?

Yeah, I did.

0celo7

16:05

@Huy Yes, but some stuff you have to do manually.

And I'm 60 hours into my save, I'd be pretty upset if it got damaged.

Huy

Yeah, but not most of them, at least it wasn't too exhausting with my hundreds of mods.

That's understandable.

Maybe stick to 8.1 for a bit till you've seen enough of Skyrim for a while and then go on.

You have a year to update, right?

0celo7

I almost died when I thought my 200h char on Xbox died in an HDD crash.

Huy

:(

I played lots of Mario Kart 64 on my xBox with my friends

0celo7

@Huy The problem is getting patches to work.

I can put a shitload of mods on, but getting them to work like they do now was a huge pain.

Huy

I see.

Then maybe better wait.

0celo7

16:07

@Huy Did you crack it?

Huy

I can understand it would be frustrating if it didn't work.

0celo7

@Huy I think so.

Huy

Yeah, built in some Aladdin modchip.

Was 14 at the time, scared as hell to brick it.

0celo7

@ACuriousMind I emailed the Math/Physics librarian and she said they did not get the German books because no one on campus has ever needed one before.

I can order it though.

My Xbox is 500 miles away.

Huy

@0celo7: I might be getting a Macbook soon. Shame they're all so bad performance wise.

0celo7

16:09

Pro?

Huy

My xBox is 5 meters away.

No, I prefer the new one.

0celo7

They're not bad performance wise considering how portable they are.

Oh the really little one?

Huy

I got a great PC at home, I just want something extremely portable to do some small work with LaTeX while I'm at work/uni.

Yeah, that or an Air.

I've been trying to use my iPad Air 2 to TeX, but it's not remotely as good as on a proper PC.

Kyle Kanos

@Jim: you're towards the top of this list (highest median score)

Jim

I think I'm slipping. I've had a lot more zero-score and low-score answers lately. More than ever before in my answer history

0celo7

16:10

@Huy Ugh, that sounds horrible.

Jim

So I expect that number has dropped

Huy

@0celo7: The most difficult part was actually getting used to the OSX layout of the keyboard. It's quite different, especially for TeXing.

@0celo7: Quite a shame the Air has no retina display. :(

Jim

@KyleKanos median score? That's not a great indicator. Average score would be more accurate for users with >100 answers

Kyle Kanos

Except having a few HNQ answers will totally skew your average

That's why you should look at mean & median

Huy

@0celo7: You went for the Pro because you wanted gaming, or was there a different reason?

Jim

16:14

that's why you only check those with a lot of answers. That way it dilutes the HNQ answers

Kyle Kanos

My median is 3, but my mean is 3.7

So it's close

Jim

my median is 3 but my mean is 5.45

Kyle Kanos

Wait, sorry; my median is 2

So yeah, HNQ still skews the mean

0celo7

@Huy It's what my Mac fanatic father got.

John Duffield

@obe: it isn't just Einstein I refer to. I refer to other physicists, some contemporary, and moreover I refer to the evidence. And we aren't just talking relativity here. See this for example.

0celo7

16:18

@Huy Really?

I'm very close to getting my keyboard, I should have a test parcel from home arriving shortly.

@Huy Indeed.

Jim

It's not the HNQ posts, I just have a question get around 10 votes every so often. It's a result of answering only the questions I know I can answer well.

But HNQ does help

and someone always getting answers on HNQ posts must be doing something right

The Hot Network Questions are the enemy of this site. They lead to pop-sci being far more upvoted than actually interesting physics questions.

Huy

@0celo7: Swiss German layout keyboards are very different to US or German. A friend of mine doing his MSc in CS has no problems switching from OSX to Windows every day, because he is using a US keyboard layout on both (which makes a lot of sense for programming). So I think you'll be fine.

I think I'll watch some movie. Laters.

Kyle Kanos

Dumb questions like "Why does my light through the door look like this" get HNQ because it's easily accessible, despite not being a good question

HDE 226868

I wonder if Physics is an exception in that some HNQ questions can hurt the site.

Jim

16:23

@JohnDuffield See, that's a good post. It doesn't rely on your opinions or what some famous person said. It gives the viewpoints of physics and explains them. This is why I wrote that fringe physicists are valued members of our community. You know your stuff, even if occasionally we butt heads

0celo7

Am I really dumb because I never noticed the HNQ thing before you complained about it?

Kyle Kanos

I could be biased because I answered it, but I do think that the "Why are rockets so big" question is actually a good question to ask

Despite the easily-found answer via Google

Jim

@KyleKanos I agree. Of my top 5 answers, only #2 is worthy of being highly voted. The others were just mindless things that I intuited mostly or wrote funny things for. Not proper and good physics

+56/-4. I assume the downvoters were severely annoyed.

Jim

yes. probably

I never even noticed it was downvoted

But I know someone made a meta post complaining that they're answer was downvoted but something like this was upvoted

And someone tried to edit out the short/long answer part of it. I rolled it back, obviously

It's an appropriate way to answer the question. It's just not a good question

@KyleKanos not sure how I put the wrong and more effort "they're" into it. I'm ashamed, but it's better than "there"

davidZ has 700 answer, median score of 3 and average score of 5.9. I think with that many answers. it's safe to say he just gets a lot of votes. I don't think his HNQ posts are offsetting that many others so significantly

Can I mention that I'm not actually fond of wormholes myself. If you read Einstein's 1935 paper with Rosen it isn't what you'd expect. IMHO wormholes appeal to Einstein's authority without much justification. — John Duffield 31 mins ago

Duffield saying Einstein's authority is not perfect?

Jim

16:39

woo, #9 on that list

@0celo7 okay, lay off the guy. Now we're crossing into the realm of being intentionally offensive

DanielSank

@0celo7 Nobody's authority is "perfect". Heck, in science nobody's "authority" should be considered worth much at all, IMHO.

Kyle Kanos

I'm pretty sure my authority is perfect

DanielSank

@KyleKanos Nah. I just checked. You're rated at 68.3%.

Apparently I'm only a 57%.

@KyleKanos Yes, but you are one of the products of the Law of Exceptions

DanielSank

@KyleKanos Woooo highest average score in my weight group [at least among users returned by that script]

Kyle Kanos

@DanielSank Well 68 is a good number

@0celo7 A sugar momma or sugar daddy?

DanielSank

17:38

@KyleKanos It is?

Kyle Kanos

Well I'm sure it has its uses, like most every other number

Jim

@KyleKanos It's definitely better than 67, at any rate

Kyle Kanos

At least 1 better

Jim

stupid useless prime number that's so out in the middle of everything that nobody would find it useful

67 is a crazy number..... It's all sixes and sevens

0celo7

@KyleKanos That was a serious question.

Kyle Kanos

17:48

I don't know what it was in reference to though

0celo7

HD backup.

Seriously, what are these percentages?

@DanielSank I did.

Kyle Kanos

OOooooh

That makes sense

0celo7

I want to backup before I update Windows.

Kyle Kanos

I'd just get a HDD enclosure and a large-ish HDD that fits it

0celo7

Wow those are cheap...any preferred software?

Kyle Kanos

17:52

Software?

It's an enormous folder

Drag & drop

0celo7

So you just want me to back up files, not make a bootable clone of the HD?

Kyle Kanos

Well if that's what you're doing/wanting, that's beyond my pay grade

0celo7

My linear algebra recitation does not have a time or place...just a date: tomorrow.

Kyle Kanos

Hmm, well guess you'll spend all day there?

0celo7

Hmm, I could put everything on my 1TB OneDrive. @Huy does that sound like a reasonable backup?

@Huy Makes me wonder: say I copy a Steam game onto a stick and delete the game. Then I put the game back on the stick. Will it play or do I have to do a proper download again?

@KyleKanos Are TAs addressed as professors?

Jim

17:57

@0celo7 wherever you are, you'll have to recite linear algebra all day tomorrow

0celo7

I have to email the TA about the recitation.

Jim

@0celo7 what's the context? Don't call them professor

0celo7

I need to have a greeting in the email, no?

Jim

marker/grader? Lab instructor? Tutorial leader?

0celo7

"recitation instructor"

Jim

17:59

Sir or Ma'am might do. If you know their name, use that

0celo7

I know that

Jim

I had a student call me "Mr. TA" once

I responded with "Mr. TA was my father..."

0celo7

Mrs. TA?

I knew it

Kyle Kanos

@0celo7 No. Unless they are actually a professor to the university, they're not professor or doctor or ?

0celo7

@KyleKanos Title is not listed

Kyle Kanos

18:00

If they don't explicitly say, "Call me ... " then ask what they should be referred to as

0celo7

I've never met the dude

Kyle Kanos

In class, I mean

Jim

no, if a masters degree teaches a course, they can be called "Professor" by the students taking that course

0celo7

I might never meet him unless I figure out when and where this class is

Kyle Kanos

Do you have his name?

0celo7

18:01

Yes

Kyle Kanos

Good. There's this thing called "Campus Directory" that you can use....

Jim

use that

0celo7

the campus directory does not give the title

@KyleKanos I'm not that much of an idiot.

Jim

What's the name?

Kyle Kanos

Then just Google his name

0celo7

18:01

@KyleKanos huh

Kyle Kanos

0celo7

math.utk.edu/~dydak/myWebPage/welcome.php

he is a professor :D

Jim

Even still, I usually just say "Hi Jerzy,..."

but I'm a really informal person, so that may not be your style

0celo7

can someone please tell me what these percentages are

Kyle Kanos

They're a reflection of your authority

0celo7

18:07

by what metric

Kyle Kanos

The standard metric of authority

@0celo7 Apparently you'll find that out when you find out what is the ultimate question of life, the universe, and everything

please

Jim

I'm not entirely sure myself. But I don't care enough to ask or to suggest possible meanings

0celo7

> As for how his plan would be paid for, Walker said it would not be funded through new taxes

@KyleKanos I thought we wanted to lower taxes.

@Jim please care

Jim

They are just numbers he used in a conversation that only minimally involved me. I don't have any reason to care what the numbers are about

If I said you ranked 48% while DavidZ ranked 72.6%, would it really bother you?

Kyle Kanos

@0celo7 We do. But if you restructure how taxes are done, it could be that a new tax is created by removing another.

Not saying that Walker is planning that, but it's a line of thinking

0celo7

18:34

@Jim DS said I was 20%

obe

@Jim Can I be 3.57%?

Jim

@obe Yes, absolutely

0celo7

I want to know what that 20% is

Kyle Kanos

@0celo7 Nothing really

Jim

@0celo7 without context, it's the same as an arbitrary number he made up. Don't focus on it so much

Kyle Kanos

18:36

2 hours ago, by DanielSank

@0celo7 Dude, you're like a 20%.

That was the context

DS invented a number for Ocelto and he's now thinking it actually means something

Jim

^ my point. There was no context

Kyle Kanos

Oh, I thought you had missed the context entirely

Jim

no, I saw it. I might have misused the word "context", however

0celo7

@KyleKanos it has to have meaning

Jim

Most things do. That's no reason to let it bother you

Kyle Kanos

18:40

@0celo7 Well, you'd have to ask DanielSank about it

John Duffield

I'm not a fringe physicist, I'm actually the opposite of that. Allow me to demonstrate...

@0celo7 : the Einstein-Rosen "wormhole" paper isn't actually about wormholes. Don't you get it yet? There are charlatans and quacks out there who appeal to Einstein's authority whilst flatly contradicting the guy in order to peddle all sorts of specious pseudoscience woo. Like "whether you can go back in time is held in the grip of the law of quantum gravity".

0celo7

@DanielSank please explain what 20% means.

Kyle Kanos

My guess is that you had just asserted your authority & Daniel was joking by putting you at a low number, such that have no authority

Jim

@JohnDuffield We all have a subject in which we are fringe physicists. Some of us don't show it as much. You may not be a fringe always, but you, like everyone else, are sometimes. Don't worry about it.

0celo7

@KyleKanos maybe, but then I've been uselessly wondering about it for the past 20 minutes

Kyle Kanos

18:43

@0celo7 Correct, you have been uselessly wondering about it for anywhere between 20 minutes and 2 hours

0celo7

oh wow time flies

John Duffield

@Jim : no really, I'm not fringe at all. Really. And if I'm not, that means...

Jim

fringe doesn't mean "wrong"; it means "outside the mainstream viewpoint while still in the realm of validity"

0celo7

???

John Duffield

@Jim: I refer to Einstein etc. Which means I'm inside the mainstream viewpoint. Which means...

0celo7

18:45

^^ this so much

Kyle Kanos

@0celo7 Well what'd you send to him?

0celo7

@KyleKanos I said I didn't see a recitation when I signed up and thus I'm unsure about scheduling problems.

I wanted a time and a date

Jim

@JohnDuffield how many times have we argued about the local constancy of $c$? A locally constant $c$ is the accepted mainstream viewpoint. Actually, there's a number of posts of yours I can call as examples. You know your stuff and acknowledge the mainstream, but there are many examples of where your posts emphasize alternative valid theories, etc. You are fringey. Nothing wrong with that. Can be grating to disagree all the time. But nothing wrong with it

I'd also call annav a fringe physicist

0celo7

what's she fringey about?

Jim

and there are a few others that are bordering on moving from fringe to full on crackpot

@0celo7 I can't put my finger on it. She's subliminally fringey

John Duffield

18:51

@Jim: a variable coordinate speed of light is mainstream too. The popscience myth that claims to be mainstream is that the speed of light is absolutely constant. It isn't. That isn't mainstream. That flatly contradicts Einstein and the evidence. That's cargo-cult science. That's fringe. I'm not fringe. And if I'm_not, I'm afraid _you are.

Kyle Kanos

I don't think annav has fringe positions

Jim

@JohnDuffield Yeah, variable coordinate $c$ is mainstream. For sure. But lemme call up an example of what I mean. Gimme a sec

0celo7

blackboard says I have 16 assignments due tomorrow

John Duffield

Oh no, he's going to quote Sean Carroll at me. Or Brian Greene. Or Max Tegmark.

Kyle Kanos

Ha, got it to work: Average Answer & Question scores

@DanielSank: I think I'm an expert at SQL now. What was your query?

Jim

18:54

@JohnDuffield no, I'm looking through your posts for great examples. Not every post is fringey, obviously, but there have been a few I remember

John Duffield

@Jim : I don't make this stuff up. I'm not some my-theory guy. When you find a post, follow my links. And when it doesn't square some with some time-travel crap from Kip Thorne, don't blame me.

0celo7

???

Kyle Kanos

> QED is a Latin acronym meaning "Touchdown Tennessee"

Nice

Jim

@JohnDuffield I know that. Fringe physicists don't make stuff up. They use valid and published theories that aren't yet mainstream. Like focusing on f(R) gravity instead of dark matter/energy. Or those people who used to only believe in MOND

Kyle Kanos

Of course, the Vols suck, but that's besides the point.

@0celo7 I am pretty sure that every school that hires a new coach says that

John Duffield

@Jim : if you want to look at what I've said about dark matter/energy, see this. The guys who tell you WIMPs are the only game in town will try to make you think that what they say is mainstream and everything else is fringe. It isn't true, but of course 17-year-old kids like 0celo7 believe it, hook line and sinker. So much so that they think they know better than Einstein. They don't.

0celo7

@KyleKanos or when they sign RG3 for a ludicrous amount of money

Jim

19:06

here's a good one: physics.stackexchange.com/a/198240/23473

Kyle Kanos

If by RG3 you mean the current Washington Redskins QB, then he wasn't signed for ludicrous amounts of money (4 years $21 mil is actually a lot, but not for an NFL contract)

0celo7

the consensus is that he's worth nowhere near that much

but I might be wrong I guess

Kyle Kanos

Well when he was signed, he was worth that much

And his rookie year, he played well. Until the knee injury

And he's been mediocre since

0celo7

his contract was extended after the injury, no?

Kyle Kanos

Nope, new union rules don't let rookie contracts be restructured until after 4 years of play

John Duffield

19:14

@Jim : that answer is dripping with rock-solid reference. I hate to break it to you, but Einstein isn't fringe. Nor is the arXiv. What we have here is a bad case of if I don't know about it, it must be fringe.

OK, I have to go I'm afraid. Bye for now.

Jim

@JohnDuffield Not true. Fringe physics is published and referenceable. A friend of mine just published a paper on a subject that was fringe physics up until a couple years ago. Non-mainstream means it isn't attracting a lot of attention. It doesn't mean wrong or not published

another is this

not necessarily wrong, any of it. And well-referenced. But it expresses opinions or theories that are not the most widely held. That makes it fringey. That's why I say we all are fringey sometimes.

You are confusing my usage of "fringe" with how some use "crackpot". I'm not talking physics by old pros that have gone off the deep end. I'm not talking Alcubierre Warp, just a tendency to prefer theories or ideas that are valid but not the same as the most widely held theories or ideas

actually, a couple of your posts mention how your interpretations are more in line with the spirit of what Minkowski and Einstein meant when they were writing their works and not in line with the modern interpretation of those works. That, by my definition, makes it fringe

John Duffield

@Jim : watch my lips. Einstein isn't fringe, and nor am I. Your further example is where I'm pretty factual and I make it clear when I'm giving opinion. The edge thing at the end relates to Neil Cornish and his "hall of mirrors". Again if I don't know about it, it must be fringe.

Jim

it is not the case where I am classifying things as fringe purely due to my own ignorance

Also, I can't watch your lips. Just fyi

Perhaps we have differing definitions of "fringe"

John Duffield

19:31

@Jim : I hate to break it to you, but some of what you think of as "modern interpretation" is just bad physics from popscience quacks and wannabees. Now apologies, I really must go. Meanwhile try to find some more of my answers where I'm allegedly "fringe", and it will be the same story. I'll refer you to something legit which is flatly contradicted by your "modern interpretation", and you never knew.

Jim

not sure if you've read it, but I wrote a meta post that explains multiple types of users. I'm not sure if I'd say you exactly fall into the category, I wrote it with a different user in mind (actually 3 different users), but I describe a "fringe physicist" user. It's not bad. It's like someone that focuses on the big bounce as the most likely theory

A: Why some people insist one unlikely possibility?

There are a few different types of users that can be known to behave like this. Some we can do something about, some we can't, and some we can but shouldn't. The first type of user likely to exhibit this behaviour is the "next Einstein" user; one that is not well-studied in physics and has thoug...

Does the fact that exp(a+b)=exp(a)exp(b) and that exp(x) forms an abelian group under multiplication follow trivially from exp'(x)=exp(x)?

Jim

19:47

not trivially. At least, it's not trivial to me

NeuroFuzzy

@Jim well, I'm trying to show the isomorphism between one-parameter subgroups of a Lie group, and the lie algebra itself, from smooth manifold definitions

and all i have is the smooth manifold equivalent of $\exp'(s)=\exp(s)$...

And I feel like it would be cheating to use power series expansions to show that the resulting subgroup is abelian and all that stuff...

(b/c they'd be power series expansions of matrices, and also b/c that's ugly)

Jim

if it's ugly, how is it cheating?....... said the misogynist

NeuroFuzzy

Hehe okay, i feel like there has to be a way easier way to do it

HAH

edit

Jim

@NeuroFuzzy probably is. I don't know it. But I seriously doubt it's mathematically trivial

Huy

@0celo7 I don't know, I guess so. I personally prefer to put important stuff both on cloud and some different HDD (internal or external), but I just like being extra sure.

NeuroFuzzy

@Jim GOT IT! Suppose $f(0)=1$ and $f'(x)=f(x)$. Then consider $g_s(x)=\frac{f(x+s)}{f(s)}$. $g_s'=g_s$ (piggyback on the properties of $f$) and $g_s(0)=1$, so $g_s(x)=f(x)$ by the uniqueness of solutions to ODEs.

But $g_s(x)=f(x)$ is just $f(x+s)/f(s)=f(x)$, or rather $f(x+s)=f(x)f(s)$.

Q: DISCUSSIONS section

Physics is a field that should be up for interpretation always, and consistently being challenged by people who can think differently. Just as Galilean relativity was improved by Einstein's theory of relativity, and Newtonian (Classical) mechanics was added on by the ever-growing field of Quantum...
